(ci. sts-4o) My invention relates to improvements in a warm airregister. It is adapted especially to controlthe inlet of warm air intoa room along the perimeter of the floor. The use of warm air inletsalong the junction of the floor with the side wall of a room isadvantageous for many reasons. One of the problems with registers ofthis type is control of the air flow through the register outlet. It isthe purpose of my invention to provide a register with simple, strongand durable mechanism for maintaining an outlet from the hot air inletinto the room of the desired size or closing the outlet entirely.

The nature and advantages of my invention will appear more fully fromthe following description and the accompanying drawings.Y It should beunderstood, however, that the drawings and description are illustrativeonly and are not intended to limit the invention except insofar as it islimited by the claims. l

Figure 6 is a detailed sectional view illustrating a slightmodification.

Referring now to the drawings, the warm air register vertical embodyingmy invention comprises an elongated shell adapted to fit over a warm airinlet to a room through the floor of the room at the side wall thereof.The shell has a back panel 10 adapted to rest against the side wall of aro'om in the position usually occupied by the base board. The panel 10has a top ledge 11 bent forward and provided with a down turned flange12. At the ends of the back panel 10 there are end plates 13 and 14 thathave right angular flanges115 and 16 at their back edges that fit insidethe back panel and are secured thereto as by spot welding or othermeans. Bottom channels 17 and 18 have their ends flush with the ends ofthe panel 10 and extend along the panel 10 part way toward the center toleave a bottom opening between their inner ends, 19 and 20. The channels17 and 18 have their rear flanges 21 and 22 extending upward inside theback panel 10 and afhxed thereto by spot welding or other means. The endplates 13 and 14 have bottom flanges 23 and 24 overlapped with thebottom channels 17 and 18 and affixed thereto.

The front of the register is composed of a preformed sheet member 25 anda dellector plate 26 aflxed thereto by spot welding or other means. Eachof the end plates 13 and 14 has a front flange 29 to which the sheetmember 25 is fastened by a screw 30. The member 25 has a floor engagingflange 31 thereon extending forwardly from its lower edge. The dellectorplate 26 has its lower pon Ice tion 26a bent away from the member 25 toreceive the front flanges 27 and 28 of the channels17 and 18. The endsof the deilector plate 26 are cut off shorter than the ends of themember 25 so that they do not overlap the front flanges 29 of the endplates 13 and 14. The top of the member 25 is folded over to provide asmooth rounded edge 32 and to. give added strength along this edge whichis an edge of the outlet opening of the register. It will be observedfrom Figures 3 and 4 that the member 25 is bent along three lines thatrun the length of the member 25. These bends provide the horizontalfloor engaging flange 31, a vertical portion extending up from theangeand carrying the deflector plate 26, a rearwardly inclinedintermediate portion and the folded over top portion which is furtherinclined rearwardly. In addition to providing the register with apleasing front surface, this construction provides adequate strength inthe member 25 to withstand the wear and tear of everyday use in a home.

The construction thus far described comprises a register shell which isprovided with a bottom inlet opening of the full width of the shell, butclosed off at its ends by channels which support the shell on a floor.The shell also has an upper outlet opening extending the length of theshell but spaced forwardly from the back panel and in a plane angularlydisposed to the vertical to direct air out into a room in which it isinstalled at a distance from the room wall against which the back panelis placed. My invention includesa damper 33 in the register which actsto regulate the area of the outlet opening and as a baille cooperatingwith the deflector plate to direct the warm air away from the back panelto the outlet opening.

The damper 33 is a plate which extends full length of the register. Ithas a rearwardly directed top section 34 fitting closely to` thedepending llange 12 on the top ledge 11 of the back panel 10. A fingerpiece 35 is provided on the damper 33. The damper 33 is bent slightly at'36 along a line that extends the length of the damper to stillen it andhas a flange 37 at its lower edge bent down and forward to extend towardthe front of the register at an angle of about 45 degrees to the damperitself. This forms a V-shaped nose 38 at the lower edge of the damper 33which nose bears against the back pane1 10 and the back flanges 15 and16 of the end panels 13 and 14.

The nose 38 is yeldingly pressed toward the back panel and the damper 33is supported to keep the top section 34 up against the flange 12 by astrip 40. The strip 40 is struck out of the back panel 10 as illustratedin Figures 3 and 4, or it is a separate strip 40', spot welded orotherwise affixed to the back panel 10 as illustrated in Figure 6. Thisstrip 40 or 40' has a right angular lip 41 along its top edge behindwhich the flange 37 of the damper 33 hooks. In all positions of thedamper 33 the llange 37 makes an angle of less than degrees with thestrip 40 so that the tendency of strip 40 is to force the flange 37upward against the lip 41.

The strip 40 and the back panel 10 are of sheet metal having sufficientresilience to yield enough to allow one to move the damper 33 betweenthe positions illustrated in Figures 3 and 4. Also the frictionalengagement of the nose 38 with the panel 10 and the flanges 15 and 16 isenough to hold the damper in any position to which it is adjustedbetween these two limiting positions.

It is believed to be clear from the foregoing description and thedrawings that the register constructed in accordance with my inventionprovides a simple durable mechanism for controlling the llow of warm airthrough it into the room in which it is installed. It also is readilycleaned by removing the front member 25 after which the damper 33 can beswung down until it is easy to separate the flange 37 from the lip 41.All of the mechanism is made of sheet metal which is be readilyprotected against rust and corrosion. The exterior can be painted ordecorated without in any way affecting the operation of the damper.
